5. Setup and Stop
4.4 System Installation Requirement
Figure 4.15 is a simple guidance for installing a solar system with PV inverter. A DC isolator
is required to be installed in the system between the PV panels and the inverter.

4.5 Grounding
Solis-2.5K-2G must be earthed securely. Inside the inverter, the earth wire is in yellow and green.
When the inverter is connected to the grid through the AC grid terminal connector, the earth
wire will be connected to the Earth and hence ensure safety.
5.1 Starting the Inverter
To start up Solis-2.5K-2G, it is important that the following steps are strictly adhered to:
1. Switch the Solar Supply Main Switch (AC) ON first.
2. Switch the solar panel DC Isolator ON. If the solar panels provide normal power
supply, Solis-2.5K-2G will turn on ( the red light displays and the LCD show the model name of
the inverter ).

3. When both the DC side and AC grid side of Solis-2.5K-2G have power presented, the inverter
will prepare to generate. Initially, Solis-2.5K-2G will check both its internal parameters and
the parameters of the AC grid to ensure that they are within the acceptable limits. At
this time, the green light will flash and the LCD displays the information of INITIALIZING.
4. After 3 mins, Solis-2.5K-2G will generate electricity normally. The green light will remain
on and the LCD displays GENERATING.
WARNING:
Do not touch the heat sink when the inverter is operating. Some parts may be
hot and cause burns.

5.2 Stopping the Inverter
To stop Solis-2.5K-2G, the following steps must be strictly followed:
1. Switch the Solar Supply Main Switch (AC) OFF.
2. Wait 30 seconds. Switch the solar panel DC Isolator OFF. All the LEDs of the inverter will
be off in a minute.
